Abstract:	The CO₂-laser-induced IRMPD of CF₂CL₂/HI and CF₂ClBr/HI mixtures produced ¹³C-enriched CF₂HCl. In CF₂Cl₂/HI mixtures, the CF₂HCl underwent secondary IRMPD in the continuing pulse irradiation at the same wavenumber and fluence, yielding CF₂H₂ with a ¹³C content of 97%. Because of efficient decomposition at relatively low fluences, CF₂ClBr seems to be a promising starting molecule in two-step ¹³C enrichment.
